With 100 celebrities, actors, artists, singers, and rock stars being invited to take part in Karl Lagerfeld and Carine Roitfeld's book project
The Little Black Jacket
, the efforts to out-fabulise one another were always going to be stellar.

But leave it to the ever-cool Roitfeld to take the, er, crown. For her turn in front of Karl's lens, Roitfeld dressed as Coco Chanel herself, recreating a famous portrait of the luxury fashion house's founder from the Sixties. Really, it doesn't come more effortlessly chic than that, girls.

The Little Black Jacket: Chanel's classic revisited by Karl Lagerfeld and Carine Roitfeld
will be available in bookstores this autumn to accompany the opening of an exhibition dedicated to it in Tokyo later this month.
